Proper cleaning and maintenance of portable particle analyzers are essential to ensure accurate measurements, prolong instrument lifespan, and maintain compliance with industry standards

Portable particle analyzers are highly vulnerable to dirt, humidity, temperature shifts, and physical stress, demanding a disciplined maintenance protocol

Before operation, always examine the outer casing for signs of accumulated dust or foreign particles

Gently clean the exterior with a microfiber cloth moistened in distilled water or an approved non-scratch cleaning solution

Refrain from applying harsh chemicals—even if commonly used—unless formally endorsed, since they risk corrosion or delamination of sensitive surfaces

The sample inlet and exhaust ports are critical areas that require regular attention

Accumulated debris in these zones may obstruct gas flow and compromise measurement accuracy

Clean these areas using an anti-static brush or controlled bursts of filtered air, never direct high-pressure streams

Never insert sharp objects into the ports, as this may damage internal sensors

After each use, especially in high-dust environments, perform a flush cycle using clean, particle-free air or an inert gas if the device supports it

This helps clear residual particles from the internal chamber and reduces the risk of cross-contamination between samples

Even minor smudges on internal optical elements can significantly degrade signal clarity and analytical accuracy

These components should only be cleaned by trained personnel using manufacturer-recommended tools and solutions

Typically, optical wipes moistened with isopropyl alcohol of at least 90 percent purity are used in a circular motion from the center outward

Ensure all cleaned surfaces are fully evaporated before reinstallation or startup

Calibration is fundamental, not supplementary—it directly underpins data reliability

Adhere strictly to the vendor’s calibration timeline, adjusted for operational intensity and ambient exposure

Validate performance using accredited particle standards and maintain a permanent log of all calibration events

If the analyzer shows inconsistent readings, drift, or error alerts, perform a full diagnostic and recalibration before proceeding with further measurements

Keep a maintenance log that includes dates of cleaning, calibration, part replacements, and any observed anomalies

Battery condition is a critical factor in operational reliability

Never allow complete depletion; recharge when the battery drops below 20%, and store it at 40–60% charge during long dormancy

Avoid leaving the device in vehicles, direct sunlight, or freezing environments—they accelerate battery aging and risk component failure

Keep the unit in its padded carrying case within a stable, climate-regulated storage area

Excess moisture above 60% RH risks internal condensation that may corrode traces and connections

Replace consumable parts such as filters, tubing, 粒子形状測定 and seals according to the manufacturer’s guidelines

Visual inspection alone is insufficient—material fatigue and chemical breakdown occur invisibly

Always have replacements ready—for filters, seals, and tubing—to avoid costly delays

Use foam inserts or cushioned cases during transit and never stack items above the analyzer

Finally, ensure that all users are trained in proper handling and maintenance procedures

Clear, documented workflows minimize mistakes and align team performance with manufacturer expectations

Stay current by revisiting the handbook and checking for firmware patches or technical advisories

By investing time and care into routine cleaning and maintenance, users can rely on their portable particle analyzers for consistent, high-quality data over many years of service
